Answer:

12√5

Step-by-step explanation:

√2 × √72 × √5

√72 = 6√2

√2 = √2

√5 = √5

√2 × 6√2 × √5 = 12 × √5 = 12√5

√2 × √2 = 2

2 × 6 = 12

<h2>Solution: </h2>

√2 × √72 × √5

☛ <u>Express √72 </u>

= √36 × 2

= 6√2

☛ <u>Express √2 </u>

= √2

☛ <u>Express √5 </u>

= √5

<h3><u>Now, Multiply them; </u></h3>

√2 × √72 × √5

☛ √2 × 6√2 × √5

☛ √2 × √2 × 6 × √5

☛ 2 × 6 ×✓5

☛ 12 √5

Therefore, \sqrt{2 } \times \sqrt{72} \times \sqrt{5} is 12√5.

Ivan has 6 times as many blue beads as red beads. he has 49 red and blue beads in all. how many blue beads does Ivan have
salantis [7]

Let

x--------> the number of blue beads

y--------> the number of red beads

we know that

x+y=49

x=49-y -------> equation 1

x=6y ------> equation 2

equate equation 1 and equation 2

49-y=6y\\ 6y+y=49\\ 7y=49\\\\ y=\frac{49}{7} \\  \\ y=7

find the value of x

x=6*7\\ x=42

therefore

the answer is

Ivan has 42 blue beads
