Add together the powers.
3+4=7
Times the first numbers of the brackets together.
43=12
However, if written in standard form or scientific notation a number cannot be greater than 10. So divide it down:
12÷10= 1.2
Then multiply by 10. Then the number of powers which will be 7 (up above!)
The answer is: 1.2×10^8
=120000000
*you have to add another 1 on the end to balance the number of zeros.
Hope this helps!
