Question

5. Solve this equation
squrt 7q+8 = 8

6.
Simplify by first converting to rational exponents . Assume that all variables represent positive real numbers.
3 squrt 6^15

Answer 1

5.The given equation

√ 7q+8 = 8

Take square  each side.

( √ 7q+8 )^2 = 8^2

7q + 8 = 64

7q = 64 - 8

7q = 56

q = 56/7

q = 8

Answer 2

6.The equation is 3√ 6^15

= 3.√ 6^15

= 3.√(6^14)(6)

= 3.√(6^14)√6

= 3.(6^14)^(1/2)√6

= 3.(6^7)√6

= 839808(2.44)

= 2049131.52

The solution is 2049131.52
