A

since the 3 is outside the radical then = 3, hence

x = 9

B

using the law of radicals

× =

we can separate the factors as

× √ × √

= 2

C

+ = 11 + 5

D

×

= 2 × 3

= 6

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

ιт ωιℓℓ вєтнє fιяѕт ¢нσι¢є(α.)

convert the exponential equation to a logarithmic equation using the logarithm base (6) of the right side (36) equals the exponent (2).

ℓσg6(36)=2
