Which expression is equal to 5^4 ⋅ 5^8? a). 5^12 b). 5^4 c). 5^2 d). 5^−4

It should be A. You would keep the 5, and the exponent should be 4+8, which is 12.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
