SIMPLIFY: A3 xA9 over A4 PLEASE HELP

A⁸

Step-by-step explanation:

A³*A⁹/A⁴

Product law:Says that if the base of the number being multiplied is the same, then we can add the exponents

Therefore

A to the power of 3+9/A⁴

A¹²/A⁴

Quotient law:Says that when we divide two numbers with the same base,we can subtract the exponents

Therefore

A to the power of 12-4

A⁸

true

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
