What is 6/6 as a sum of fractions in three different ways
s2008m [1.1K]

Step-by-step explanation:

Remember that 6/6 = 1, so we can use that knowledge to our advantage.

1/2 + 1/2 is one of them, because 1/2 + 1/2 = 2/2 = 1.

1/4 + 1/4 + 1/4 + 1/4 is one of them, because they equal 4/4 = 1.

1/3 + 1/3 + 1/3 is one of them, because they equal 3/3 = 1.

Can someone please help me with this.
allsm [11]

Answer:

10

Step-by-step explanation:

Given expression is |8-6 i|.

|8-6 i| is a complex expression.

The value of<em> i </em>is –1.

By definition of absolute value, |a+b i|=\sqrt{a^{2}+b^{2}}

Now, substitute |8-6 i| in the above formula.  

\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}  (since <em>i </em>= –1)

                  =\sqrt{64+36}  (since 8^{2}=64 and                    –6^{2}=36)

                  =\sqrt{100}  (Square root of 100 is 10)

                  = 10

Hence, the value of the expression  |8-6 i| is 10.
