What is (3.5 x 10 to the fourth) to the second
when written in scientific notation with four significant digits?

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

I’m pretty sure it’s i think : /

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.
