so that is 3.5 times 10000 or 35000 then it is squared so 1,225,000,000 but to four significant digits it would be 1225 times 10^6 or on a online test 1225e+06
Exponents raised by exponents are resolved by multiplying the two exponents together . . . so distribute the exponent to the paranthesis
note: 3.5 = 3.5^1
(3.5 x 10^4)^2
(3.5^1 2 x 10^(4 2))
(3.5^2 x 10^8)
12.25 x 10^8
1.225 x 10^9
The result of ( 3.5 × 1 0 4 ) 2 is 1.225 × 1 0 9 in scientific notation with four significant digits. We obtained this by squaring the coefficient and the exponent before combining them. Finally, we adjusted it to ensure four significant figures were used.
