Find the value of 2a2+5b2 when a = -6 and b = 2 (the last 2 on 5b and 2a are indices)

        Where: a = -6 and b = 2

2 x ( -6)² +  5 x 2²

= 2 x 36 + 5 x 4

= 72 + 20

= 92

Therefore, the value of 2a²+5b² is 92

92

Step-by-step explanation:

Substitute the given values for a and b into the expression.

2a² + 5b²

= 2 ×(- 6)² + 5 × 2²

= (2 × 36) + (5 × 4) = 72 + 20 = 92

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
