Question

Express the following in standard form:

$\left(i\right)28\left(ii\right)100\left(iii\right)144\left(iv\right)1296\left(v\right)2100$

Answer 1

$\left(i\right)28=2\times 2\times 7=2^2\times 7^1$

$\left(ii\right)100=5\times 5\times 2\times 2=5^2\times 2^2$

$\left(iii\right)144=2\times 2\times 2\times 2\times 3\times 3=2^4\times 3^2$

$\left(iv\right)1296=2\times 2\times 2\times 2\times 3\times 3\times 3\times 3$ $=2^4\times 3^4$

$\left(v\right)2100=2\times 2\times 5\times 5\times 3\times 7$ $=2^2\times 5^2\times 3^1\times 7^1$
