Question

determine o valor das expressoes abaixo

a) 16.(-1/2)elevado a 3 -(-18). √1/36

b) (1/2+1/3).(-5) elevado a -1 + √0,01

PRA HOJE PORFAVOR!!

Answer 1

a) 16 * ( -1/2)³ - (-18) * √1/36

= 16 * (- 1/8) + 18 * 1/6

= - 2 + 3

= 1

b) (1/2 + 1/3) * (-5)⁻¹ + √0,01

= (3/6 + 2/6) * ( -1/5)¹ + √1/100

= (5/6) * (-1/5) + 1/10

= - 5/30 + 1/10

= - 5/30 + 3/30

= - 2/30

= - 1/15
