a) 2³•2⁴•2⁵•2⁶
b) (2³)²
c) (6:3)³
d)10³•10•10
e) (3⁴)-³
f) 6⁴:6²
g) (2•3)³
h) 7¹⁵:7¹⁰
i) 10-¹•10²•10-¹​

Answer 1

a) 2³•2⁴•2⁵•2⁶ = 2¹⁸

b) (2³)² = 2⁶

c) (6:3)³= 2³

d)10³•10•10 = 10⁵

e) (3⁴)-³ = (1/3⁴)³ = (1/27)³

f) 6⁴:6² = 6²

g) (2•3)³ = 6³

h) 7¹⁵:7¹⁰ = 7⁵

i) 10-¹•10²•10-¹ = 1/10 . 10² . 1/10 = 100/10
