Simplify the expression so there is only one power for each base
5.6^-5 x 3.4^-7 x 5.6^3 x 3.4^-4
answers-
a) 5.6^-6 x3.4^-3
b) 5.6^-2 x 3.4 ^-11
c) 5.6^-8 x 3.4^-7
d) 5.6^-8 x 3.4^-3
e) 5.6^8 x 3.4^11

So, Correct option is B i.e

Step-by-step explanation:

The expression here contains exponents so, we will use exponent rule.

The exponent rule says that the power of the same bases can be added if two same bases are multiplied i.e.

using this rule we can solve our question

So, Correct option is B i.e

Answer

step-by-step explanation

For the expression

we rewrite the expression to get

One of the laws of indices states that

which means that if multiplying expressions of the same bases, repeat one of the bases and add the exponents

This implies that

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
