Hi,

- You have to raise four to the power of three. --> 4³ = 64 Is this how you would say it?

- What do you call the line between a numerator and a denominator ? Is it a fraction line?

- Is this called 'the cube root of 64'? "The cube root of 64 is 4."

Thank you.

Ann225You have to raise four to the power of three. --> 4³ = 64 Is this how you would say it?

is read as "four cubed". "four to the power of three" is also correct, but usually we would say "cubed".

"You have to raise four to the power of three" is correct English, but it is not clear to me exactly how it is meant to relate to "4³ = 64 Is this how you would say it?"

Ann225- What do you call the line between a numerator and a denominator ? Is it a fraction line?

The usual term is "fraction bar".

Ann225- Is this called 'the cube root of 64'? "The cube root of 64 is 4."

Yes, that's right.

Thank you. Could 4³ be also read as ‘four to the third’?

You can forget about the part with 4³ = 64. Emotion: smile

Ann225Could 4³ be also read as ‘four to the third’?

Yes, I believe some people do use that (short for "third power", I guess).

Four cubed.

Four to the power of three.

Four to the third power.

The forward slash symbol is the dividing line. 4 / 3

Thank you both. Emotion: smile

What is five cube+7⁶=

According to my calculator,

53+76 = 117774.

However, this is not a grammar question.

Please ask math questions on a math forum.
