Will give
in which expression should the exponents be multiplied?
2^9 over 2^7
(6^10) ^-7
(1/2)^3 • (1/2) ^5
5^2 • 5^4

Step-by-step explanation:

Apply the power rule of exponents: .

From the given options, the only expression in this form is

When we apply the above rule, we get:

All the other options are of the form:

The correct choice is the second option

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

1/4 because there is 4 grades.
