Answer»

Question 158(iii)

Find a single machine that will do the same job as the given hook-up.

$a (\times 5^{99})$ machine followed by a $(5^{- 100})$ machine.

Maya multiplied $(4^{2} \times 3^{2})$ by thinking about stretching machines.

Use Maya's idea to multiply $5^{3} \times 2^{3}$ .

Maya's idea is another product law of exponents.

Multiplying Expressions with the same Exponents

$a^{c} \times b^{c} = (a \times b)^{c}$

You can use this law with more than two expressions. If the exponents are the same, multiply the expressions by multiplying the bases and using the same exponent. e.g. $2^{8} \times 3^{8} \times 7^{8} = (2 \times 3 \times 7)^{8} = 42^{8}$ .
