Estimate the sum of 299 and 388
Svetllana [295]

For this case we have the following numbers:

299

388

Let's round up each of the numbers to the nearest hundred,

We have then:

299 = 300

388 = 400

We note that now we have two numbers whose approximation is easier to add.

We have then:

300 + 400 = 700

Answer:

The sum of 299 + 388 is approximately:

700

Could someone help me with this please and thank you!! <br> Will mark and star!!
timurjin [86]
The rule for expressing a radical as a rational exponent is as follows:
\sqrt[n]{x^y} = x^ \frac{y}{n}
So, to find \sqrt[3]{27x^2y^3z^4} use that rule.
The cube root of 27 is 3, so the equation will start with 3.
3x^ \frac{2}{3} yz^ \frac{4}{3}
Hope that helps!
