Question

Match the following numbers with their corresponding powers.

• A. $2^9$
• B. $4^5$
• C. $3^7$

Answer 1

$3^7=3\times 3\times 3\times 3\times 3\times 3\times 3$
$=(3\times 3\times 3)\times (3\times 3\times 3)\times 3$
$=27\times 27\times 3$
$=2187$

$2^9=2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2$
$=(2\times 2\times 2\times 2)\times (2\times 2\times 2\times 2)\times 2$
$=16\times 16\times 2$
$=256\times 2$
$=1024$

$4^5=4\times 4\times 4\times 4\times 4$
$=(4\times 4)\times (4\times 4)\times 4$
$=16\times 16\times 4$
$=256\times 4$
$=1024$
