Write seven cubed in all three forms: exponential, expanded and standard form

Yeah you have to write it so the answer would be like seven or something

Mark Brainliest please

Exponential form: 7^3
Expanded form: 7*7*7
Standard form: 343
Step-by-step explanation:
The exponential form is when we use the ^ symbol. The base is the number before the ^ and the exponent is the number after the ^. When seven is cubed, the base is 7 and the exponent is 3.
Therefore, the exponential form is 7^3. We can also write it with a little 3 on the top right corner of the 7, that is .
On the expanded form we use multiplications. The exponent number tells us how many times to multiply the base number by itself. When 7 is the base and 3 the exponent, we have to multiply 3 times the number 7 by itself. That is 7*7*7.
The standard form is the result of the calculations we wrote before. The easiest way is to get it from the expanded form.
7*7*7 = 49*7 = 343

Ithink the answer is b.
