Answer:
Your answer would be 51.
Step-by-step explanation:
Remember the mathematical sequence: PEMDAS
P=parenthesis
E= exponents
M=multiply
D=divide
A=add
S=subtract.
In this case, there are no parenthesis and there are no exponents, so we multiply. Then there is no divide in this equation, so we go straight to add and subtract. Remember to do all this in the order of PEMDAS.
Answer:
Step-by-step explanation:
It helps immensely if you know your times tables.
a) 36 = 6*6 = 2*3*2*3 = 2^2*3^2
b) 45 = 5*9 = 5*3*3 = 3^2*5
c) 2 is not a common factor; 3^2 is a common factor; 5 is not a common factor. The greatest common factor is 3^2 = 9.
d) The least common multiple can be found a couple of ways.
.. 1) the product of the distinct factors to their highest powers
.. .. .. 2^2 * 3^2 * 5 = 180
.. 2) the product of the numbers divided by their greatest common factor.
.. .. .. 36 * 45 / 9 = 180
