$14+\frac{3^2}{6}$ or $\frac{14+3^2}{6}$ or $\frac{(14+3)^2}{6}$ ?

Hi Dan,

My computer doesn't have the symbols for math but it is the second problem you listed. I am also trying to find the square of 1/6 and 2/5

Thank you for your help 14 + 3squared

Hello, duckpluckie!

My computer doesn't have the symbols for math

You can still type mathematical expression . . . <b>if</b> you're careful.

Use ^ for exponents . . . and use LOTS of parenthese.

14 + 3^2 . . . means: 14, plus 3² . . . or 14 + 9 = 23

If you want "fourteen plus 3, all squared", write: (14 + 3)^2

"14 plus 3 squared divided 6: 14 + 3²/6 = 14 + (9/6) = 14 + 1½ = 15½

If you want "fourteen plus 3 squared, all divided by 6", write: (14 + 3^2)/6

but it is the second problem you listed: $\,\frac{14\,+\,3^2}{6}$

My book says $21$ . .?? . . . no way!

All you need to do is use a calculator for these ones. Just type in $\sqrt{\;\;\;}$ and then type $\left(1\div6\right)$

$\frac{14+3^2}{6}=\frac{14+9}{6}=\frac{23}{6}$

Since 23 is prime, this fraction is simplified as far as it can go, so we are done.

Hi, duckpluckie,

if your book says that the result is 21 then there is a typo:

$\frac{14\cdot 3^2}{6}=\frac{14 \cdot 9}{6}=14\cdot\frac{3}{2}=21$

Bye
