Use the Product Rule of Exponents to simplify 510⋅55

To simplify 510⋅55 using the Product Rule of Exponents, we can add the exponents of the same base number, 5.

Following the Product Rule, we get:

510⋅55 = (5^10)⋅(5^5)
= 5^(10+5)
= 5^15

So, 510⋅55 simplifies to 5^15.

What is the missing exponent in the following equation?

h450h? = h215 (1 point)

To find the missing exponent in the equation h450h? = h215, we can use the Quotient Rule of Exponents. According to the Quotient Rule, when dividing two numbers with the same base, we subtract the exponents.

In this case, we have:

h450h? = h215

The base is 'h'. Since the exponents are missing, let's call them 'x' and 'y'.

Using the Quotient Rule, we can write the equation as:

h^(450-x) = h^215

To solve for the missing exponent 'y', we need to set the exponents on both sides of the equation equal to each other.

450 - x = 215

Now, we can solve for 'x':

450 - x = 215

Subtracting 450 from both sides, we get:

-x = -235

Dividing both sides by -1 (or multiplying by -1), we find:

x = 235

Therefore, the missing exponent in the equation h450h? = h215 is 235.

Simplify 1287÷1225 .

To simplify 1287 ÷ 1225, you can simply divide the numerator (1287) by the denominator (1225).

1287 ÷ 1225 = 1.05

Therefore, 1287 ÷ 1225 simplifies to 1.05.

To find the value of 6.9 - 2^0, we need to evaluate the exponent expression first.

2^0 is equal to 1, since any number raised to the power of 0 is equal to 1.

Therefore, the expression simplifies to:

6.9 - 1 = 5.9

Thus, the value of 6.9 - 2^0 is 5.9.
