It is written in standard form as -5.42 x 102
If we add up the numbers we get:
(-10 * 62) + (9 * 7) + (5 * 3) =
-620 + 63 + 15 = -542
To put this in standard form we first have to move the decimal point so that there is just one digit before it. Then we multiply this by the necessary power of 10 to get back to the original number.
In the form of one digit before the decimal point it becomes:
-5.42
As this number is now 100 times smaller than our original amount (we know it is 100 times smaller because we have moved the decimal point by 2 places to the left) we have to multiply it by 100 (which is equal to 10 to the power of 2) to get back to the original number.
To show this we now write it as:
-5.42 x 102 (minus five point four two times 10 to the power of two)

What is 3x4 plus 5x3 plus x2 - 5 divided by x 2?
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
Can you write a multiplication sentence for 4 plus 1 plus 3?
Yes 4+1=5 So 5x3=15
What is the gcd of 75 and 90?
GCD is greatest common divisor.we will write numbers in the form of their multiples.so 75=5x5x390=5x3x3x2so we have (5x3) common in both. so the ans is 5x3=15 :-)
3x plus 5 plus equals 20 what does x equals?
3x+5=20 x=5 since 5x3+5=20
What is 2x plus 3x to the second power plus 6 plus 5x to the third power in standard form?
If the original is 2x + 3x2 + 6 + 5x3, you should rearrange the terms in order of exponent:5x3 + 3x2 + 2x + 6
