Question

What is s²t-10 if s=-8 and t=
`(3)/(4)`

Answer 1

38

Explanation:

When
`s^(2)t-10`, s = -8 and t = 3/4

=
`-8^(2) (3)/(4) - 10`

= 64
`(3)/(4)` - 10

= (16 * 3) - 10

= 48 - 10

= 38

Answer 2

38

Explanation:

Substitute the given values into the expression

(- 8)² ×
`(3)/(4)` - 10

= 64 ×
`(3)/(4)` - 10

= (16 × 3) - 10

= 48 - 10

= 38
