22. a) (3¹)⁵

b) ⁵√(3²⁵)

c) (3⁵)³ ÷ (3⁵)²

23. The distance from the Earth to moon is 22⁴ miles

The distance from the Earth to Neptune is 22⁷ miles

The distance from the Earth to Neptune is greater by = 22⁷/22⁴ = 22⁷⁻⁴= 22³miles.

It is greater by three times

24. 8³. 8⁻⁵= 8³⁻⁵= 8⁻²= 1/8²= 1/64

1/64 ∠ 1

The student is not correct as 1/64 is less than 1.

Answer:

z = 66

Step-by-step explanation:

RS = z

QT = z - 33

Based on the midsegment theorem, QT = ½(RS)

Plug in the values

z - 33 = ½(z)

Multiply both sides by 2

2(z - 33) = z

2z - 66 = z

Add 66 to both sides

2z = z + 66

Subtract z from both sides

2z - z = 66

z = 66
