The first thing I would do would be to multiply the decimal by itself, then write the
result inside the parentheses, get rid of the original decimal in there, and throw away
that little 2 after the parentheses.
That is 1/9x2
Seven squared is 49, or 49.0 in decimal form.
You can turn the fraction to a decimal and then just add a decimal to where it is needed in the problem.
To convert metres squared to feet squared divide by (0.3048)2. In this instance, rounded to two decimal places, 67000 metres is equal to 67000/(0.3048)2 = 721182.00 feet squared.
assuming that there are no parentheses around the (7-1) then it should be 10.7
That is 1/9x2
Seven squared is 49, or 49.0 in decimal form.
Zero. (Regardless of where the parentheses are supposed to go.)
(3y2)4*3y2*3y2*3y2*3y2 = 38*y16 = 6561y16
You can turn the fraction to a decimal and then just add a decimal to where it is needed in the problem.
0.4822530864
4 squared plus 4 squared divided by 4 plus 4
102,030,201
2704.000
The same as the 8th decimal place of Pi itself.
It is 0.0000597529
And what is the question?If you want to factor that, first take out the common factor of 2, and put whatever remains in parentheses. Then you can use the rule to factor the difference of two squares, to factor what remains within parentheses.
