Question

x⁷ . x . x⁴

3⁵ . 4⁵

8⁵ . 2³

Answer 1

`a, = x^(7+4+1) = x^12`

`b, = (3.4)^5 = 12^5`

`c, = 2^15 . 2^3 = 2^18`

Answer 2

a: \(=x^{7+1+4}=x^{12}\)

b: \(=12^5\)

c: \(=2^{15}\cdot2^3=2^{18}\)

Answer 3

\(x^7.x.x^4=x^{7+1+4}=x^{12}\)

\(3^5.4^5=\left(3.4\right)^5=12^5\)

\(8^5.2^3=\left(2^3\right)^5.2^3=2^{15}.2^3=2^{18}\)

Answer 4

`x^7 . x . x^4 = x^(7+1+4) = x^12`

`3^5 . 4^5 = (3.4)^5 = 12^5`

\(8^5.2^3=2^{3^5}.2^3=2^{3.5}.2^3=2^{15}.2^3=2^{15+3}=2^{18}\)

Answer 5

a) \(=x^{7+4+1}=x^{12}\)

b) \(=\left(3.5\right)^5=12^5\)

c) \(=2^{15}.2^3=2^{18}\)
