find the numerical equivalent of 9^9 x 9^-6
To find the numerical equivalent of 9^9 x 9^-6, we can use the rule of exponents which states that when multiplying powers with the same base, we can add their exponents.
Therefore, 9^9 x 9^-6 becomes 9^(9 + (-6)) = 9^3.
Now, 9^3 can be calculated as 9 x 9 x 9, which is equal to 729.
So, the numerical equivalent of 9^9 x 9^-6 is 729.
what is the missing number in this simplified exponential expression 7^? divided by 7^5 = 7^12
To find the missing number in the simplified exponential expression, we can use the rule of exponents which states that when dividing powers with the same base, we can subtract their exponents.
In this case, we have 7^? divided by 7^5 equals 7^12.
Using the rule of exponents, we subtract the exponents: ? - 5 = 12.
To solve for the missing number, we can add 5 to both sides of the equation: ? = 12 + 5 = 17.
Therefore, the missing number in the simplified exponential expression is 17.
7^? divided by 7^5 = 7^12
To find the missing number in the equation 7^? divided by 7^5 equals 7^12, we can use the rule of exponents that states dividing powers with the same base is equal to subtracting their exponents.
Therefore, we can rewrite the equation as 7^(? - 5) = 7^12.
According to the rule, the exponents on either side of the equation must be equal.
So, ? - 5 = 12.
Adding 5 to both sides of the equation, we have ? = 12 + 5 = 17.
Therefore, the missing number in the simplified exponential expression is 17.

what is the value of 6.9 - 2^0
The value of 2^0 is 1, as any number raised to the power of zero is always equal to 1.
Therefore, the expression 6.9 - 2^0 becomes 6.9 - 1.
Subtracting 1 from 6.9, the result is 5.9.
So, the value of 6.9 - 2^0 is 5.9.
