4.7 x 10 to the sixth power.
0.545 to times ten to the negative sixth power = 0.545 x 10^-6(This equates to 0.000000545)
2.93E5, or 2.95 times 10 to the 5th power. The difference between "scientific notation" and "engineering notation" is that scientific notation generally has one digit before the decimal point and can have any exponent, while engineering notation uses exponents divisible by 3; so, 3, 6, 9, 12 and so on. So in "engineering notation", this number would be 293 times 10 to the 3rd power, or 0.293 times ten to the sixth power.
9.3 times 10 to the sixth
4,360,000
4.7 x 10 to the sixth power.
Easy.. 805, 005,849.
75,000,000 written in scientific notation would be 75 x 10^6. This could also be expressed as 75 x 10 to the sixth power, because you would move the decimal in 75 to the right six spaces.
1,400,000
1.725896 x 10^6 = 1,725,896
0.545 to times ten to the negative sixth power = 0.545 x 10^-6(This equates to 0.000000545)
