729 = blank to the third power

Mathematics
1 answer:
Crazy boy [7]3 years ago

One way is to factor and group and get every 3
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=( \sqrt[3]{3*3*3})( \sqrt[3]{3*3*3})=(3)(3)=9

the answer is 9

Answer:

\mathsf {x = 76}

Step-by-step explanation:

The given pair of angles lie on a line, hence they are classified as linear angles. They possess the property by which their sum is equal to 180°.

\textsf {Solving :}

\implies \mathsf {x + 17 + 87 = 180}

\implies \mathsf {x + 104 = 180}

\implies \mathsf {x = 180 - 104}

\implies \mathsf {x = 76}
