Use the multiplication property of exponents to determine if each statement is true or false.
lisabon 2012 [21]
1)
LHS:
{a}^{4}  \times  {a}^{3}  \times a \\  =  {a}^{4 + 3 + 1}  \\  =  {a}^{7}
LHS = RHS. So, the statement is true

2)
LHS:
{5}^{2}  \times  {3}^{4}  \\  = 25 \times 81 \\  =  {5}^{2}  \times  {9}^{2}  \\  =   {45}^{2}
LHS not equal to RHS. So, the statement is false

3)
LHS:
{x}^{6}  \times  {x}^{0}  \times  {x}^{2}  \times  {x}^{3}  \\  =  {x}^{6 + 0 + 2 + 3}  \\  =  {x}^{11}
LHS = RHS. So, the statement is true.

4)
LHS:
7 {m}^{2}  \times 2m \times 4 {m}^{5}  \\  = (7 \times 2 \times 4) {m}^{2 + 1 + 5}  \\  = 56 {m}^{8}
LHS = RHS. So, the statement is true.

Fittoniya [83]

Answer:

The probability you see a dolphin or a whale on both days is 0.64

Step-by-step explanation:

Consider the provided information.

It is given that the brochure claims an 80% chance of siting a dolphin or a whale.

The provided claims can be written as: 80% or 0.80

Let say first day you see a dolphin or a whale and same happen on the next day.

Thus, the probability is:

0.80 × 0.80 = 0.64

Probability of see them on both days is 0.64

Hence, the probability you see a dolphin or a whale on both days is 0.64
