What is the answer when Ab is not equal to 0 -12a cubed times b squared over 6ab squared?
-2a^2
What is 18 divided by 2a if a 3?
If ( a = 3 ), then ( 2a = 2 \times 3 = 6 ). Therefore, ( 18 ) divided by ( 2a ) is ( 18 \div 6 = 3 ). Thus, the result is ( 3 ).
If fx equals 2x plus 5 find f a plus h minus f a divided h?
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
What is 2 to the power of 0 why?
20 = 1Consider what is the value of 2a ÷ 2a? Any number divided by itself is 1. Thus:2a ÷ 2a = 1The law of indices says that when dividing, they are subtracted, for example:25 ÷ 22 = (2 x 2 x 2 x 2 x 2) ÷ (2 x 2) = 2 x 2 x 2 = 23 = 25-2So 2a ÷ 2a is (also):2a ÷ 2a = 2a-a = 20Since any number subtracted from itself is 0 (= a - a). This must have the same value as before, thus:20 = 1The 2 above can be replaced by any number x which means that any number to the power 0 is 1:x0 = 1
A plus a plus a-2a equals?
a + a + a - 2a = 3a - 2a = a
