Use exponents to write the # 81 three different ways

.

Step-by-step explanation:

We have been given  a number 81. We are asked to write 81 using exponent in three different ways.

First of all, we can write 81 raised to 1 exponent as:

.

We also know that 81 is square of 9, so we can write 81 as:

We know that 9 is square of three, so we can write 81 as:

Therefore, our required three different ways would be .

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
