Simplify the expression (x to the fourth power times x cubed)squared/x to the 4.
a)x
b)x to the fifth
c)x to the tenth
d)x to the 20
I kind of confused. I tried to divide by 4, but i couldn't get anything. I need help?
What is the simplified form of 30 times x to the sixth power over 14 times y to the fifth power times the fraction 7 times y squared over 6 times x to the fourth power?
Well, let's break it down step by step:
First, let's simplify the expression inside the parentheses: (x to the fourth power times x cubed) is equal to x to the power of (4 + 3) which is x to the power of 7.
Next, let's square x to the power of 7: (x to the power of 7) squared is equal to x to the power of (7 x 2) which is x to the power of 14.
Finally, we divide x to the power of 14 by x to the power of 4: x to the power of (14 - 4) which is x to the power of 10.
So the simplified expression is x to the power of 10, which means the correct answer is c) x to the tenth.
Remember, math isn't as scary as it seems! Keep practicing and it will become easier.
To simplify the expression, let's break it down step-by-step.
Step 1: Apply the power of a power rule.
(x^4 * x^3)^2 = x^7^2 = x^14
Step 2: Divide by x^4.
x^14 / x^4 = x^(14-4) = x^10
Therefore, the simplified expression is x to the tenth power.
The correct answer is:
c) x to the tenth
To simplify the expression ((x^4 * x^3)^2) / x^4, we can break it down step by step. Let's start:
Step 1: Simplify the exponent of (x^4 * x^3)^2
(x^4 * x^3)^2 simplifies to (x^7)^2. We multiplied the exponents inside the parentheses because we have the power of a power rule.
Step 2: Apply the exponent to the expression (x^7)^2
(x^7)^2 means we multiply the exponents, so it becomes x^(7*2) = x^14.
Step 3: Simplify the denominator by dividing the x^4
x^4 / x^4 = 1. When we divide two terms with the same base but different exponents, we subtract the exponents.
Now, we have x^14 / 1, and any number/1 is just the number itself.
Therefore, the simplified expression is x^14.
So, the answer is (c) x to the tenth.
[x^4*x^3]^2/x^4 = (x^7)^2/x^4 = x^14/x^4 =?
Remember that exponents get added when you multiply and subtracted when you divide terms of the form x^a, if all terms are powers of x
For example x^a*x^b = x^(a+b)
(x^a)^b = x^(ab)
x^a/x^b = x^(a-b)
Now you complete that last step.
